Related bugreports: #261087 Synopsis Multiple integer overflows in the Ghostscript ICC library might allow for user-assisted execution of arbitrary code. 2. Impact Information Background Ghostscript is an interpreter for the PostScript language and the Portable Document Format (PDF). Description Jan Lieskovsky from the Red Hat Security Response Team discovered the following vulnerabilities in Ghostscript's ICC Library: Multiple integer overflows (CVE-2009-0583). Multiple insufficient bounds checks on certain variable sizes (CVE-2009-0584). Impact A remote attacker could entice a user to open a specially crafted PostScript file containing images and a malicious ICC profile, possibly resulting in the execution of arbitrary code with the privileges of the user running the application. 3. Resolution Information Workaround There is no known workaround at this time. Resolution All GPL Ghostscript users should upgrade to the latest version:
Code Listing 3.1: Resolution
    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-text/ghostscript-gpl-8.64-r2"
All GNU Ghostscript users should upgrade to the latest version:
Code Listing 3.2: Resolution
    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-text/ghostscript-gnu-8.62.0"
We recommend that users unmerge ESP Ghostscript and use GPL or GNU Ghostscript instead:
Code Listing 3.3: Resolution
    # emerge --unmerge "app-text/ghostscript-esp"
For installation instructions, see above. 4. References CVE-2009-0583 CVE-2009-0584 |
